I noticed that when I am coming to a stop there is a popping sound, that sounds like a metal to metal contact, or close to what a failed bushing sounds like. It is faint, but sounds unnatural. Dealer states that they can not hear any noise, and have it on a lift looking at it. It only happens when coming to a stop, and occasionally when you take off. Might have to go up there, and drive with the technician. Any one else hear this sound?
